I did 3 more runs this morning before I went to work, I keep getting those damn cloth robes, cloth shoulders, or the friggin boots. I've seen the cloak twice...

I started at about half way through friendly and soon as I hit exalted I threw my hands up and thought WTF?! All I do is kill the 2 mini-bosses and the 1st boss, then open the cache, I stopped keeping track of how many runs I've already done lol.

And I will continue to run mech up to the cache until I DO get all 5 needed lol. On the plus side I've built up a ridiculous amount of enchanting mats.
